are accessible to the'workman without requiring. him to move from a single position in which it is Convenient for him to work. The tools are mountedon a single'planetary device or turret on which they are rotated to and from working position, moving in turn-into operative position in frontoof the workman. In this position they are operatively driven in, rotation,.'each tool in turn being preferably locked inoperative position by a device which .performsthe'locking operation simultaneously with the.engag'ement of a clutch which drives the tool or tools to operate them atthe will of the workman. In addition to the arrangement ofthe machine in this way, a feature of the machine of almost equal importance .is a dust collecting device which cooperates with each toolinworking position, providing a more efiicientitakeup or collection and withdrawal of'the dust than has been accomplished in any machine of this general type whereby the diffusion through the atmosphereof the dust resulting from the grinding and similar operations which has been a very objectionable feature of this work hasbeen completely eliminated. I

In the accompanying drawings I have illustrated the machine of the invention in the preferred form.

Referring to the drawings by numerals, each of which is used to indicate the same or similar parts in the different figures,v the machine shown comprises a machine base I, supported on an upright standard 2, on which is mounted a hood 3, including a bracket or frame member 4,, on which the turret shaft 5 is supportedin suitable bearings at both ends.

The turret carries the various rotary tools referred to;

This turret may be rotated by hand by workman who engages manually the hand the ring also includes a suction fan 8 and an ele motor 9 for driving thev machine.

ct i

This motor in the preferred form illustrated is mounted on i the fan shaft or the fan is mounted on the motor Shaft.

The machine is controlled, stopped and started and the selected tool-on'the turret is driven the turret is held in the operative position of each tool or tool shaft in turn by means clutch unit It which in the form -of the invention shown is controlled by a clutch pedal ll. This in the preferred form in addition to operating the clutch serves to shift simult ously with the engagement of the clutch a anebolt

by which the clutch is driven. Thejconstruction also includes a changespeed belt shifting vice comprising low speed pulley l2 and high speed pulley M, the belt being shifted in suitable manner by hand or otherwise. A

any belt and buffer 28, 29 and brushes 30 and bufferj 3l and other tools to be further described.

, The turret shafts-also carry outside the turret at the left in Figure 1, having reference to the shaftsZD, 2|, 22 and 24 in turn, the top lift trimmer 32, edge setter stone 3 3, sole trimmer 34 and heel breast wheel 35, the members 32,2 33, 34 and 35 being preferably 50 arranged; they co-operate with the tools inside the;

that

ret on the same shaft in the sense that the tools placed on any single shaft are tools which the workman wouldbe apt to use success ively or nearlyat the same time, asfor instance, the sole trimmer 34, the grinder 25 and the buffer -26;

The machine also includes a grinding stone 31 mounted on a clutch shaft 38, Figure 8,

from which stone the workman is protecte a hinged'cover 39.-

tur- Referring again to the turret 6, this is rotated from the driven position of one shaft 20, 2|, 22, or 24 in which position the tools thereon are rotated so that they can be used in the operative sense by the workman, to the next selected operative position, by rotating the tur ret in any suitable manner. In the form shown, the turret is rotated by manual engagement of the hand wheel 1. The turret is located in the operative position of each of the respective shafts just referred to'by means of a bolt 48, see Figure 8, which in the preferred form illustrated is advanced simultaneously with the closing of the clutch It! as hereinafter more fully described.

In the preferred form of the invention shown, each of the tool shafts 20, 2|, 22, 24, carried by the turret is provided on its end next to the clutch ID with a clutch disk or driven friction disk 43, see particularly'Figures l and 4, to be engaged and driven by the driving disk 44, Figure 8, carried by the clutch shaft 45 and shifted longitudinally thereof, into and out of operative or engaging position at the will of the operator as aforesaidn The clutch shaft 45 and'the clutch disk 44 thereon, which is keyed to the shaft to slide relatively thereto, are driven continuously from the motor shaft 46 which also carries the fan 8 by means of a belt 41 which is driven from the high speed pulley I4 or the lower speed pully i2 on the motor shaft, the change of speeds being optional with the' perator. The pulleys I4 and I2 correspond to the high and low speed pulleys 48 and 49 on the clutch' shaft which are driven by the belt l5 as aforesaid driving the clutch shaft and the tool which is in operative position at the high or low speed selected by the operator.

Referring particularly to the details of the clutch mechanism as shown in Figure 8, the clutch shaft 38 is mounted in suitable bearings in the clutch housing 50. This shaft carries the driving disk 44 on a sliding sleeve 5|. keyed to the shaft and siidable along the shaft. A tendency on the part of the driving disk to advance to the left into engagement with the driven disk 43, which happens to be in operative position is imparted thereto by helical springs 53 compressed between the back of the disk 44 and the front of a second or spring abutment disk 54 mounted on a ball thrust bearing 55 rotated with the sleeve 5! and the disk 44. At the right hand end the sleeve 5! carries rotatively mounted thereon a collar 56 which cooperates with the sleeve and engages the same by way of a ball thrust bearing 51. This collar 56 is providedwith trunnions 58 projecting laterally and engaging a clutch lever 59 pivotally mounted at 6B in the clutch housing and having an arm 6| which approaches in its position a line parallel to the clutch shaft 45,

being adapted to swing downwardly therefrom in the operation of the mechanism to withdraw thedisk 45 to disconnect the drive from the shaft 2!), 2|, 22 or 24, which happens to be in operative position, the clutch driving disk 44 being shown in Figure 8 in its withdrawn position in which it is released.

The clutch lever 59 may be described as of the bell crank type in that the throw of the operating arm 62 is at right angles to the throw of the actuating arm 6|. The upper end of the operating arm 62 of lever 59 in the'form of the invention shown is provided with a ball 64 which fits in a pocket or slot 65 in the sliding bolt 45 which engages selectively at the will of the operator any one of a series of holes 66, see Figure 5, in the adjacent surface of the right hand head 1 of the turret or planetary member E3. The actuating arm 6| of the clutch lever 9 is connected to the foot pedal H by means of a strap or connecting rod 68, see Figure l, and in the operation of the machine the operator having first pressed the pedal and then rotated the turret to bring any particular tool, selected by him for use, into operative p sition, the pedal is then released and the springs 53 advance the driving disk 4| into engagement with the corresponding disk 43 on the shaft 2!), 2i, 22 or 24, which carries the tool to be used and the bolt 40 being advanced by the arm 52 of the lever 59 due to the action of the springs engages the corresponding positioning hole 66. It is necessary to rotate the turret until the corresponding hole registers with the bolt and positions the disk in exact alignment before the clutch can be engaged, giving an automatic positioning of the turret in operative relation to the clutch before the clutch can be engaged or the tool shaft operatively rotated.

The dust collecting system whereby diffusion of the dust from the buffing, grinding and brushing operations, is prevented, is an important feature of the machine. For this purpose a suction fan 8 is mounted on the motor shaft 48 in the fan housing or casing 79, see Figure 1.

Referring to Figure 5, it will be noted that the right hand turret head 1 is provided with a series of dustladenair openings H arranged around the axis of the head and spaced outwardly by an equal radius. These openings may be provided in any suitable manner, one for each tool shaft 20, 22, 24. The dust laden air opening corresponding to the shaft 2! is omitted because this is a brush shaft and comparatively little, if any dust is generated by the brushes, although suitable provision may be made for the takeup ofthe dust from the brushes if desired without departure from the principles of the invention or the teachings of this disclosure.

Referring now to Figure 4, it will be noted that there is a dust hood for each of the tools which is regarded as generating dust or sufficient dust to merit the provision of means for taking up the dust and discharging it to the outside. In Figure 4, there is shown one of three dust laden air ducts 72. This duct extends along the turret parallel to the axis spaced outwardly therefrom bya convenient distance, the duct being preferably located between the corresponding tool shaft 20 which is shown in this instance, and the turret shaft 5.

In the form of the invention shown the air duct 12 is of increasing tapering cross section from the left. At this point it is provided with a hood i3 enclosing the top lift trimmer 32, the end portion of the duct being offset radially at 14. The increasing taper extends to the right hand head 1 of the turret to which the duct is secured by a flange 15 which is bolted to a corresponding boss on the head I in which boss the corresponding one of the openings i! already referred to is formed. At the left the small end, i. e. the duct 72 passes through the head 6 and joins the radial passage 14 carrying the hood 13 which is secured to the face of this head or disk by means of a flange H, which is bolt-ed or fastened in any suitable manner.

The tapered duct l2 carries the hoods or housing 13 enclosing the corresponding elements or tools 25, and 1'9 enclosing the tool-2a, and the other air ducts E2 of which there arethree in all, in the form of the invention shown, carry hoods cooperating with finishing tools which require this provision or all of the tools or finishing olemerits may be thus provided with hoods.

Referring now to Figure 6, it will be noted that the fan housing T is provided. with a suction chamber-' preferably concentric therewith and surrounding the shaft 4%. This vacuum chamber 89, see Figure 6, is connected atthe top by a passage 8i to an opening 32 in the faceoi the turret head I. The openingBZ and pipe 8| are stationary and the discharge openings H of the dust laden air ducts 112 which rotate with the turret, register in turn with this opening 82 in the operative positions of the head, i. e., the operative positions of the corresponding tools mounted on shafts 2t], 22, 24. In this way 'a'relatively high vacuum with an inward rush of air is established at the hoods l3, l8, l9, enclosing the various operative members or tools 32, 25, 26, etc, having reference to all the tools which are thus protected. This air draft picks up and carries all of the dust generated at the tools inwardly through the hoods to the duct 12 and is not shown and which is downwardly to the vacuum chamber 80 whence it passes to the fan chamber 8, being ejected by the fan through the lateral passage 83. Figures 6 and7, into a suitable chamber 34in the base 2 whence it may be removed through the door 35 or carried downwardly into the basement or otherwise disposed of. The illustration also includes a nipple 8?; see Figure. 1, for the attach- 1 ment of the hose of a vacuum cleaner or the like whereby any dust which accumulates in the system may be withdrawn and the brushes, etc., may be cleaned. The air is discharged from the base through a suitable separating screen which no part of the invention. I

The vacuum arrangement described is of considerable advantage as compared to other machines of the ordinary turret typehaving dust hoods and a vacuum'system "whereby the dust laden air is withdrawn through the turret shaft, as'with the arrangement of the present invention the ducts IZare of unlimited sizeand anygdesired taper is permitted whereby a uniform vacuum is maintained throughout the length of the duct as the capacity of the duct increases in proportion tothe volume of air admitted. With the present apparatus an, absolutely complete absenceof dust from the workroom is maintained and the workmen and others entering the room are completely andfully protected from the. dust laden air whichis known to have ex- I ceedingly harmful. efiects.
